Safety in School Construction. 

Many advances have been made during recent years in the design and construc- 
tion of school buildings. Scientific study and thorough investigation has been given 
to such features as the arrangement of rooms, better lighting, improved ventilation, 
modern sanitation, fireproofness, soundproofness and economy. The many improve- 
ments in modern schools have resulted in a higher standard of scholarship and of 
health among the students. 

"Safety First" is a brief expression v^hich indicates the prominence of the pres- 
ent-day movement for the better protection and safeguarding of human lives. No- 
where should this appeal have a greater consideration than in the construction of 
school buildings. Here are housed hundreds of little children w^ith neither the strength 
nor the experience to protect themselves in the face of such dangers as fires. 

The necessity for fireproof construction of schools is nov^ generally recognized by 
School Boards and tax payers. There is no need to picture the horrors of a Collings- 
v/ood calamity nor the long list of school fires occurring every year. The lessons of 
these disasters have been well learned by thinking people. The laws of many States 
now^ require fireproof construction throughout for schools of any size, and even in the 
smaller buildings fireproof corridors, stairs and boiler rooms. There is no doubt but 
that every section of the country vs^ill adopt similar laws in the near future. 

The cost of fireproof construction has been greatly reduced by the introduction 
of reinforced concrete in building schools. Fireproof, modern schools now cost little 
if any more than the old style, inflammable building, with masonry w^alls and wood 
joists. Reinforced concrete is used in many parts of the building, including floors, 
roofs, stairs, partitions, ceilings, etc. The exterior design may be of masonry, brick 
or concrete as desired. 

The proper distribution of daylight throughout the rooms (usually obtained 
from one side only) requires serious consideration in the construction of the windows. 
The use of modern steel sash assures maximum daylight from the window openings. 
There are no wide mullions or muntins to obstruct the light. 

The following pages indicate a few suggestions for the proper construction of 
schools, as well as a number of photographs of typical installations. The wide extent 
to which Kahn Building Products have been used in school buildings has given our 
engineers an exceptional experience along these lines. Their suggestions are sure to 
be useful and are furnished free of all obligation.

Floor Construction for Schools. 

FIREPROOFNESS : By making the floors of schools fireproof, the greatest fire danger is elim- 
inated, because the fire can then be confined to one locality without communicating to floors above 
or below. The earlier methods of constructing fireproof floors usually involved steel girders with 
heavy arches. The great expense of such construction often made its use prohibitive. The 
introduction of reinforced concrete not only reduced this cost but brought many other advantages, 
such as flat ceilings, lighter weight, simplicity, etc. Various types of reinforced concrete are used, 
including steel Floretyle, reinforced terra cotta tile, reinforced solid concrete, etc., as indicated in 
the following pages. 

SOUNDPROOFNESS : Floors of reinforced concrete are soundproof — an important advantage in 
schools. Steel Floretyle and reinforced terra cotta tile are very superior in this respect, owing to 
the insulating qualities of the dead air spaces in the tile. No noise or sound can possibly be 
communicated betw^een floors. 

STRENGTH AND SAFETY: Numerous tests under severe conditions by Public Building Bureaus 
and on actual installations have repeatedly demonstrated the exceptional strength of reinforced 
concrete construction. These tests include not only heavy load, but severe fire tests. The test 
loads on actual floors have often been four times the required carrying capacity, without show- 
ing any signs of weakness. Reinforced concrete floors are also very rigid and free from vibration, 
as demonstrated in many industrial buildings w^here heavy vibrating and pounding machinery is 
placed directly on the floor. 

SANITATION: Reinforced concrete floors insure the best sanitary conditions. Being of masonry 
construction there is no lodging place for germs or vermin of any kind. Compare this with w^ooden 
construction with its open timbers and its tendency to become damp and unsanitary. 

ECONOMY: Reinforced concrete is much more economical than any other construction w^hen 
one considers its permanence and the saving of insurance. As a matter of fact, when reinforced 
concrete floors are properly combined with other features of the construction, the first cost is little 
if any more than the old style buildings with wood joists. Its economy in the long run can be 
readily demonstrated by actual comparative figures. 

FLAT CEILINGS: School rooms are ordinarily from 20 to 30 feet in width and it is desirable 
to have a flat ceiling over them with no projecting beams to collect dirt and interfere with light- 
ing. This is readily accomplished on long spans by the use of Floretyle or reinforced terra cotta 
tile construction, and in shorter spans by reinforced solid concrete. In all cases the floor con- 
struction spans the full width of the room, giving an absolute flat ceiling free of all beams and 
projections. Compare this with the earlier types of fireproofing w^ith steel girders, which not only 
had beams projecting below the ceiling, but which were considerably more expensive. 

FLOOR FINISH: Any type of finished floor may be laid upon the reinforced concrete construc- 
tion. Ordinarily a wooden floor is desired and can be readily obtained by placing small wooden 
sleepers on top of the construction, filling in between them with cinder concrete and attaching 
the finished floor to them. Finished floors of cement, tile, terrazzo or composition are often laid 
on the concrete construction, particularly in corridors, auditoriums, etc.

STEEL FL0RETYLE5- 




Sectional view of 
^ Floretyle construction 
from above. 

Steel Floretyles, the Ideal Construciion 
for Floors in Schools. 

Steel Floretyle construction as shown in the illustration, consists of rows of hollow steel tile, 
separated by reinforced concrete joists and covered with a thin layer of concrete. These narrow 
joists carry the loads directly to the supports, while the Floretyle act merely as fillers, saving 
concrete and reducing dead weight. Hy-Rib extends continuously underneath and provides a 
flat ceiling and a perfect surface for plastering. 

The many advantages of Steel Floretyle Construction make it particularly adapted for school 
floors. Flat ceilings over all rooms are assured as spans up to 30 ft. and greater can be readily 
secured without the use of any intermediate beams. Furthermore, this ceiling construction is light 
in weight, owing to the heavy masses of concrete that are saved by the hollow Floretyle. The 
reduced weight makes a corresponding saving in all the supporting construction. 

Soundproofness of floors is assured by the insulating qualities of the dead air space formed 
by the Floretyle. These open spaces also greatly simplify the location and the installation of 
ventilator flues of which a great many are required in modern schools; also conduits and pipes 
can be readily carried along the length of the Floretyle without cutting or weakening the con- 
struction. 

The great strength of Floretyle construction has been repeatedly demonstrated by elaborate 
tests, and hundreds of installations in important buildings. The Railway Exchange Building in

Note the true lines of joists and the great rigidity of Floretyles. 

St. Louis is a block square, twenty-one stories high, and contains over thirty acres of Floretyle 
construction. A full-sized panel of this Floretyle construction was built under severest weather 
conditions and tested with a load of 491,651 lbs., without showing any sign of weakness. 
Numerous other tests have been madr such as for the Marcus-Whitman School described on next 
page. Floretyle construction has bee:, approved and passed by the Building Bureaus of all 
principal cities of the country. 

Floretyle construction is very simple to install. Labor, time and material are saved by the 
simplicity of the centering, the large size of the Floretyles and the wide spacing of the joists. 
This construction can be used with equal success in all parts of the country, as the Floretyle and 
reinforcement are readily shipped at low freight rates.

Floredome Construction. 

Steel Floredomes present all the advantages 
of Floretyle construction, but are adapted for 
two-way construction in which the loads are 
carried in two directions to the supports. The 
metal domes are deeply corrugated to secure 
stiffness and are only open on the underside, 
so that the joists extend on all sides of the 
dome.

An Exhaustive Test on Floretyle Construction 

for Marcus Whitman School, Spokane, Washington. 

In this remarkable test Floretyle Construction developed a strength five times as great as 
the load for which it was designed. The test w^as conducted prior to the construction of the 
Marcus-Whitman School on a full-sized panel having a clear span of 26 feet and width of 5 
feet 3 inches. The construction was designed for a safe live-load of 75 pounds per square foot. 

The floor consisted of three concrete joists, each reinforced with one Kahn Trussed Bar 
and separated by steel Floretyle of standard design, 1 in. deep and 20 in. wide. The total 
thickness of the slab was 1 3 in. The test was conducted very carefully with the co-operation 
of the City Engineer and his assistants. Deflections were accurately measured at 9 points in 
the span by means of instrument readings upon bolts imbedded in the concrete. 

The slab was originally loaded with 20,500 lbs. of pig iron equal to 150 pounds per sq. 
ft., with a maximum deflection of 13/32 in. After the removal of the load, the slab returned 
to practically its original position. 

On the following day, the slab was tested to its ultimate carrying capacity. Under a 
loading of 20,500 pounds, the deflection was .27 inch, equivalent to 1/1100 of the span, 
while the City Building Code allows a deflection as great as 1/700 of the span. No cracks nor 
signs of weakness were apparent under this loading. 

The test was continued and the deflections under loadings of 30,800 pounds, 41,000 pounds, 
and 51,000 pounds, were .56 inches, .92 inches and 1.5 inches. Above this loading the deflec- 
tions increased gradually until over six inches before failure occurred at 52,000 lbs. This load 
is equivalent to 375 pounds over every squaie foot of floor, or five times the load for which 
the slab was designed. This test, as w^ell as numerous others, prove conclusively the w^onder- 
ful strength, safety, and rigidity of Floretyle Construction. See photograph of Marcus Whit- 
man School, page 38.

Reinforced Hollow Terra Cotta Tile Construction. 

Terra Cotta Tile Construction possesses many of the advantages of Steel Floretyle Construc- 
tion, but to a much more limited degree. In this construction also, the hollow tile are separated 
by reinforced concrete joists which carry the full weight of the construction, assuring flat ceil- 
ings of long span, extending across the w^idth of the room. Terra Cotta Tile, however, is much 
heavier than Steel Floretyle and, therefore, increases the w^eight of the floors; also the joists 
are 16 in. instead of 24 in. on centers, requiring more concrete and increasing the labor in placing. 
Terra Cotta Tile is limited for use in localities near tile plants; otherwise the freight on the tile 
would make it too costly. This construction is thoroughly soundproof and fireproof, allow^s sim- 
ple installation of ventilator flues and conduits, and has been very extensively used throughout 
the country in the construction of school floors. 



Reinforced Solid Concrete Construction. 



Solid concrete reinforced with steel is frequently used for floors of schools, but is only 
recommended for shorter spans, less than 1 2 ft. For greater spans its weight would be excessive 
and Steel Floretyle or Terra Cotta Tile should be used. Where a solid concrete construction is 
desired for longer spans, intermediate beams of reinforced concrete are used. These beams 
span the width of the room and are spaced 4 ft. to 8 ft. apart, supporting a thin reinforced 
concrete slab. This type of construction affords ample strength but has the disadvantage of 
projecting beams which collect dirt, interfere with lighting and are unsightly in appearance. Solid 
concrete is also not as soundproof as Floretyle or Terra Cotta Tile, and presents greater difficul- 
ties in the location of conduits and ventilators.

Kahn System Reinforced Concrete Stairs and Floors. 



Reinforced Concrete Corridors and Stairs 

No matter what type of construction may be used in the rest of the building, the Corridors 
and Stairs should be built absolutely fireproof, so as to provide safe means of exit and to delay 
the spread of the fire. The floors of the corridors are built of any of the various types of rein- 
forced concrete previously described. Stairs and stair landings are constructed of solid concrete 
reinforced with steel and can be of any desired design to suit all requirements. Corridors and 
stairs built in this w^ay have the greatest possible resistance to fire. 



Floors Over Boiler Rooms 



All floors over boiler rooms or fuel storage rooms should be of the best possible fireproof 
construction of reinforced concrete. This is imperative, no matter what the construction of the 
Test of the building may be. Fires very frequently originate in boiler rooms and by using a 
precaution of this kind, at least one of the fire dangers is eliminated. 



10 Modern School Construction. 



General Features of Construction 

The use of fireproof construction for floors in schools has often consisted merely 
in the substitution of reinforced concrete for wood joists without affecting in any w^ay 
the general arrangement of supporting walls, both exterior and interior. In such a 
construction these walls are built heavy enough to support the floor construction, 
which spans directly between them. The light weight of Floretyle construction greatly 
reduces the loads coming on such w^alls. 

A considerable saving in the cost of the school is effected by using a frame work 
of reinforced concrete girders supported on columns in place of the heavy interior 
walls, w^hich then become merely dividing partitions. As these partitions do not carry 
any loads, they can be built very thin of Hy-Rib construction (see page 12), being 
only 2 in. thick. The saving in space is over 1 2 in. in the width of each room as a 1 7 
in. brick w^all w^ould ordinarily be required. This makes a considerable reduction in the 
width of the building, effecting material savings in all parts of the construction and 
greatly reducing the total cost of the school. Savings of this nature will often counter- 
balance the slight additional initial cost of fireproof construction. 

Some designers carry the same system of supporting girders and columns into the 
outside w^all construction, using w^hat is know^n as skeleton frame design. Outside 
walls then become light curtain walls which do not carry any loads, as the floors are 
carried at each floor level by girders and columns. The concrete construction is often 
left exposed on the exterior but some designers prefer to veneer it w^ith layer of brick 
or terra cotta. Skeleton frame construction often presents decided advantages in speed 
and economy, as the entire framework of floors, girders and columns is erected in one 
operation without the delays occasioned by building supporting w^alls. 

Any type of floor designs, previously described, may be used in connection with the 
above general methods of construction. Variations or combinations of them may be 
adopted to suit individual requirements. Our engineers would be glad at all times to 
make suggestions as to the most economical and satisfactory construction. 



Semi-Fireproof Construction 

Occasionally in small schools it is desired to reduce the cost of construction to a 
very low^ figure and at the same time secure a construction of some fire resistance. For 
such buildings, the old-style wood joists may be retained but in place of the wood lath 
ceiling, use metal lath, plastered with cement mortar. Also use this metal lath for all 
partitions and furring. This metal-lath-cement construction possesses considerable fire- 
resistance and materially retards the spread of flames. 

Old school buildings with w^ood joists and studs can be remodeled so as to be made 
at least partially fireproof by the use of metal lath and cement plaster in ceilings, parti- 
tions and walls.

Seven-Rib Hy-Rib. 

One of Three Types Furnished. 



Solid Hy-Rib Partitions. 

Hy-Rib is a steel sheathing stiffened by deep ribs formed from the same sheet of 
steel. The large sheets of Hy-Rib are attached at floor and ceiling, plaster is applied to 
both sides and the partition is complete. No studs or channels are required, and the 
expense of wiring lath to studs is eliminated. Grounds for attaching base boards or 
picture moulds are readily placed before plastering. 

Hy-Rib partitions are not intended 
to support loads, but are used gen- 
erally for subdividing the interior 
into rooms. Hy-Rib provides the 
best construction for all non-bearing 
partitions and in fact for all interior 
walls, v^here a framework of girders 
and columns support the floors. 

The completed Hy-Rib partition, 
being less than 2 in. in thickness, 
greatly increases the size of all rooms. 
Consider the great saving in space as 
compared with 6 in. to 8 in. required 
for partitions of Terra Cotta Tile or 
wood studding. By using the Hy- 
Rib partitions throughout, the size 
and cost of the school building can 
be considerably reduced ow^ing to the 
great saving in space. 

Hy-Rib partitions plastered with 
cement mortar are absolutely fire- 
proof, as has been demonstrated by 
tests of the New^ York Building 
Bureau and others. These partitions 
have exceptional strength and rigid- 
ity. The soundproof qualities of 
solid monolithic Hy-Rib partitions 
have been proven by actual tests as 
well as by practical use in schools, 
hotels, apartment houses, etc.

CEILING 



Hollow Walls or Partitions. 

Rib Lath wired to Rib Studs. 




Hy-Rib Ceilings, Mount St. Joseph Academy, Buffalo, N. Y. 



Hollow Partitions of Rib 
Lath and Rib Studs 

In some instances where many pipes 
have to be carried through partitions, it 
is desirable to have a hollow fireproof 
construction. A combination of Rib 
Studs with Rib Lath is ideal for this 
purpose. Rib Studs, as will be noted, 
consist of two vertical steel members rig- 
idly connected by cross ties formed from 
the same section of steel. The studs have 
exceptional stiffness and at the same time 
are open for the passage of pipes or con- 
duits in any direction. This design also 
affords an uninterrupted air space be- 
tween the two plastered surfaces, adding 
to the insulating qualities of the partition. 
Rib Studs are readily attached to floors 
and ceilings with Rib Stud extensions. 
Rib Lath is wired directly to the studs 
and plaster applied to the face of the lath 
on both sides of the partition. Other 
types of hollow partitions can, of course, 
be adopted, such as using Rib Lath with 
other types of studs of wood or steel. 



Hy-Rib Ceilings For 
School Buildings 

Suspended ceilings are usually required 
under roofs of schools and should alw^ays 
be fireproof. For this purpose there is 
nothing that can compare with the Hy- 
Rib ceiling. Hy-Rib, as previously de- 
scribed, comes in large sheets combining 
lath and stiffening channels. In building 
these suspended ceilings all that is nec- 
essary is to provide lines of supports 
spaced 4 ft. to 6 ft. apart, the Hy-Rib 
being attached directly to them and plas- 
tered on the under side to form the ceil- 
ing. The great saving of this simple con- 
struction as compared with lath and chan- 
nels is apparent when one considers the 
entire elimination of all expense of wiring 
lath to separate channels. 

For ceilings in semi-fireproof construc- 
tion, Rib-Lath may be attached to the 
underside of the wood joists and plas- 
tered with cement. This produces good 
fire resistance, which should materially re- 
tard the spread of the flames.

and Especially Adapted to School Buildings. 



Steel Sash for Windows 
of Schools 

Authorities generally agree that the best lighting for 
class rooms is from one side of the room only. This means 
that the maximum lighting value should be secured from 
the wall on that side and as little space as possible devoted 
to obstructing members, such as pilasters, muUions and 
muntin bars. Our modern solid steel sash is ideally suited 
for this condition, as practically no light is obstructed by 
the narrow mullions and muntins. The full area of the 
window opening is available for lighting as contrasted with 
the old style wood sash, requiring wide frames, wide mul- 
lions and wide muntins. These steel sash are also fireproof 
and permanent. 

Even greater lighting value can be obtained from the 
exterior by combining these steel sash with skeleton frame 
construction of reinforced concrete, as previously described. 
In this case the pilasters are reduced to minimum width and 
the steel windows extend continuously between them and 
up to the full height of the ceiling. By the use of these 
modern methods of construction, the daylighting of class 
rooms has been materially improved, increasing the comfort 
of the children and saving their eyesight.

A Type Well Adapted to School Buildings. 



United Steel Sash For Windows 



United Steel Sash is an improved type of solid steel sash with maximum daylighting power 
and strength. The deep narrow members offer practically no obstruction to the light. These 
steel members are united from solid steel sections under powerful presses without cutting away 
the metal at the joints, insuring the greatest possible strength and rigidity. All sash are neatly 
finished and are very attractive in appearance. 

United Steel Sash is a complete line to meet all conditions of daylighting and ventilation. 
Both pivoted and sliding ventilators can be provided. Ventilators may be pivoted just above 
the center, near the top or the bottom, or also at top and bottom to revolve on a vertical 
axis. Among vertical sliding sash, four types are provided, the counter-balanced sash in which 
the upper sash is balanced against the lower; spring counterbalances, lead counterweights and 
cast-iron counterweights. A complete line of casement sash of all types is also included. All 
sash are furnished in a large variety of sizes and arrangements. 

Our engineers would be glad to make suggestions as to the most suitable steel sash for 
any particular condition. Our United Steel Sash Hand Book completely describes and illustrates 
all types of sash, and is sent free to those interested in school building construction.

Waterproofings, Dampproofings and 
Finishes for Schools. 

A dry building is an essential requirement for the proper sanitation of schools. 
The Trus-Con Laboratories manufacture a complete line of Waterproofings and Damp- 
proofings, which insure absolute insulation from moisture in concrete or masonry con- 
struction. For instance, the Trus-Con Waterproofing Paste Concentrated is mixed with 
the water used in the concrete when the building is built or in a plaster coat on finished 
buildings, and thus insures an impervious concrete structure. 

Where the w^aterpressure from the soil is very slight, a basement can be made 
absolutely dry by applying Trus-Con Foundation Coat to the outside walls. 

Trus-Con Plaster Bond is a dampproofing product and is applied to the interior 
of outside w^alls. While dampproofing is its first function, it serves an additional pur- 
pose of forming a bond betw^een the plaster and the w^all, as it has a very tacky surface 
to w^hich plaster w^ill tightly adhere, and thus often does aw^ay w^ith furring and lathing. 

Trus-Con Stonetex is a liquid, cement, dampproof coating for stucco, concrete, 
stone, brick or other masonry surfaces. It is so formulated as to perfectly bond w^ith the 
concrete or other surfaces, and does not crack or peel off like paint. It is furnished in 
several colors and in addition to dampproofing the structure, adds to its appearance. 

During the past few years, there has been much agitation throughout the country 
over the injurious effect of both lead and oil and cold w^ater paints for the interior decor- 
ating of public buildings. Lead and oil is recognized as a poisonous material and water 
paints scale and peel off, the small particles floating through the air and acting as a germ 
distributor. Trus-Con Asepticote is a special product formulated for the sanitary fin- 
ishing of the interiors of schools, hospitals, churches, as well as private residences. It 
dries w^ith a soft dull finish, and can easily be washed v^ith warm w^ater and soap without 
in any w^ay affecting its surface. 

Trus-Con Floor Enamel is an ideal, dustless, sanitary washable finish for cement 
floors. When applied with a brush to the floors, it produces a tough, hard, elastic and 
reasonably durable finish and affords an attractive tile-like enamel finish that insulates 
and protects the floor from the direct traffic w^hich w^ould otherw^ise cause continual 
dusting and granulation of the surface. 

The Trus-Con Laboratories manufacture many other Waterproofings, Dampproof- 
ings and Technical Paints. We will gladly furnish suggestions as to the best methods 
for each individual condition, in either new or completed work. Our Trus-Con Hand 
Book describing these products gives complete specifications, etc., and is sent upon re- 
quest.

Modern School Construction. 



A Few of the Many Schools in Which Kahn System Has Been Used. 

The few illustrations shown in this book give only a meager idea of the hundreds of schools 
in w^hich Kahn Building Products have been used. The following list is only a partial one, but 
indicates our extensive experience along these lines. We are glad to place this experience at the 
disposal of those interested in school buildings without obligating them in any way. Our repre- 
sentatives are located in all principal cities and will give direct, personal co-operation at all times.
